What the Heck is Wrong with Safebooru?

Greetings all. I am AzureBlazer07, formerly Wing_Kaiser_X. I decided to create a new account because I forgot the password of my old account.

I have noticed that several images that we have here in SB are all but pixelated/ blurred images which were previously fine. Compare: http://safebooru.org/index.php?page=post&s=view&id=2386341 with https://static.zerochan.net/Kochiya.Sanae.full.2163574.jpg There is a difference in quality even if you are logged in.

Now what is going on here? I've updated my Adobe flash to the latest version already if in case you ask me to update my Adobe flash. Just asking because I really have been surprised by the quality drop in several images that suddenly came some time ago.
